granted to me there is described a method of".

feed for combing "maehine's ing feed roller is pushed along; the nipper "plate without turningjto" make the'Yfeed, or n other wordsit slides along the plate, being" prevented from turning by I a: ratchet and" p l; 'T r sw i lmaal PQSlUO J F' aQl ness for the next fee1mev 1nenuit sfro'lled backwards over "tlief material during j "the backward swing of the nipper- In er'e r to adjust the amount. of feed and the position of the roller'on 'theplate, each head of the six with which combers are usually built, had to be adjusted separately. The object of the present invention is to connect all the six iced rollers in such a manner that the amount of feed and the position of the feed rollers on the nipper plate can be altered and adjusted simultaneously by a single screw alfecting all six rollers.

In order that the invention may-be clearly understood I append a sheet of drawingsin which the invention is shown applied to. a comber constructed according to my United States Patent No. 1,369,532 but it willbe understood thatit may be applied equally well to any other combing machinein which the feed roller is carried on and swings with the nipper.

Fig. 1 is a section through the middle of a head showing the nipper and feed roller when in their nearest position to the detaching roller D and showing only such parts as are necessary.

Fig. 2 is a similar section showing the necessary parts in their opposite extreme position whilst the cylinder C is combing.

The feed roller F rests on the nipper plate P attached to the bridge B cast with the nipper cheeks N the whole swinging on the adjustable nipper pivot N and receiving its oscillating motion from the shaft W through the rod 17 and pin 16. The roller bearing 30 can be moved along and set in any position on the rod 31 which is'pivoted at 32 on the lower arm of the'right angled lever L hinged loosely on the pin 16.

Keyed 'on the shaft T is the'lever .36. having turned on one side of it aboss' on which theplate 37 .isjfadjustably Inountedfso that thelever and plate have a common center. 'The plate 37 has a projec tibn 38; cjomesagainst'a block 39 fixed on the rod 40 which extends throughoutthe,

length of the machine. 'A se'cond projection 41 on the plate 3Tcarries a set screw S so that the oscillation oflthe' plate 'and theshaft.

T 1 is adjustabl'y limited by thegap between theend oii the set; screw" and the, projection 38.If. Tli'e"'-widthof this gap determines the extent of movement (that is the amount: offeed) 'of the roller F on thei late P as will be further described below. The plate 37 has formed'in it a circular slot 42 so that it can be fixed by the screw 43 in various positions-in relation to the lever 36. The alteration of this relation alters correspondingly the position in which the feed roller F operates onthe plateP For instance for long fibre it might have to be set back on the plate so as to occupy the position indicated by the dotted lines in Fig. 2. Each roller can be set individually by positioning the bearing 30 on the rod 31 and being all set in line and the same distance lfrom the nipper point, theycan be all altered simultaneously by displacing lever 36 in relation to plate 37 as described.

Theroller F is pressed against the plate P by the spring 44 acting through the lever 45 pivoted at 46 and one end of which presses on the top of the roller bearing 30 and this frictional contact prevents the displacement of the roller on the plate except when it is forcibly displaced as will now be described.

In Fig. 1 the nipper is shown in its most forward position the "feed being just completed. It then swings backwards on the pivot N to the position shown in Fig.2 and owing to the frictional pressure on the feed roller bearing, just mentioned, the lever L on the pin 16 is carried with it and through the rod 34 and lever 35 rocks the shaft T carryingwith it the lever 36 and plate 37 until the projection 38 contacts with the fixed stop provided by the block 39' whereupon the lever L can no longer accompany its pivot 16 which continues its course causing the lever L to turn on its pivot and draw the roller F ghrough the rod 31) backwards on the plate the opposite direction, the Whole ssystem moves together until the set screvv con tacts With the stop blocl; :39 when the lever L is again arrested and the continued movement ofthe pivot 16 causes again to turn thereon and pushes the roller F along the plate, Without turning as previously described, andthus makethe feed, By Widening the ga'pbetween theset screvv' S andthe projection38 the feed is shortened and vice versa. If hilst the parts are in the position of Fig. l the screws?) be loosened and the plate 37 :held whilst the lever 36 is moved to a different position in relation thereto the shaft T? and its connections ivill move the'roller F to a different position on the plate P the displacement being limited by the extent of slot 42.
